Shot with Atik 16200 mono camera, 16, 3 minute sub exposures combined for 48 minutes total expose. This is the luminence channel only. I will get red, green, and blue to add color to the image later.
Scope used was 14" Meade ARC with reducer at approximately 2500mm focal length.
These 3 minute sub exposures are un-guided and show the true potential of the mount once guiding and periodic error correction are added.

Wow! That's a great image. In my CPC 800 that's just a wee little whirly-Q.
